Abstract
A reluctance motor with a stator ( ) which has a three-phase current stator winding for generating a rotary magnetic field and a rotor ( ) which is located on the shaft ( ) and which is made primarily of a ferromagnetic material. The rotor is formed of a predetermined number of angular regions of the same peripheral angle which adjoin one another in a circumferential direction and preferably have at least one pair of flux guidance regions ( ) facing the stator ( ), with flux guidance properties which differ in the main direction of the rotary field. According to a first feature, the stator ( ) has a preset number of angular regions of the same peripheral angle which adjoin one another in the circumferential direction, preferably having at least one pair of flux guidance regions ( ) facing the rotor ( ) with flux guidance properties which differ in the main direction of the rotary field, and the number of angular regions ( ) on the stator ( ) differ from the number of angular regions ( ) on the rotor ( ) by an integral multiple of the pole number, preferably the simple pole number, of the three-phase current stator winding. Alternatively or together with the first feature, according to a second feature, the flux guidance regions ( ) and connecting elements for connection to shaft ( ) of the reluctance motor ( ) enclose a flux guidance rotor ( ) which floats on shaft ( ) via bearings and which is made of ferromagnetic material for returning of the lines of force of the rotary field.
